FanHouse Jenny Thompson

Dara Torres, the 42-year-old swimmer who won three silver medals in the Beijing Olympics last summer, is back at it again. Despite squaring off against people sometimes half her age, she continues to dazzle. The latest? She took down Jenny Thompson's six-year-old record in the women's 50-meter butterfly.

This record was achieved in a senior circuit event, so the competition may not have been quite as stiff, but her time was still good enough for the United States record. Even more impressive for Torres, via her own Twitter page, is that she hadn't swam the butterfly since the 2000 Olympics. At all (again, according to her).

Jenny Thompson won 12 medals in her four Olympic games, the most of any U.S. Olympian in history, so you might think she'd be a source for positive comments about the Olympic experience.

But Thompson is actually somewhat pessimistic about the future of the Olympic Games, mostly because she believes that chemists who help athletes cheat with performance-enhancing drugs will always be more sophisticated than chemists who try to catch the cheaters.

In an interview with Playing the Field, she talked about that.
